🏢 Ontwa Township Office
Ontwa Township's own township government keeps its local records: council or board meeting minutes, local ordinances and resolutions, local permits and licenses, and its own budget and contracts. Requests for those records go to the township clerk under the Michigan Freedom of Information Act. In Michigan, the township clerk also runs local elections and voter registration. Birth and death certificates, marriage records, deeds and court files are generally kept by county and state offices rather than by the township; see the offices below.
